LG056: NEW-Potted Exotics: What about Olives, Lemons, and Figs??
When your client says, “I’d like something different. Something unique,” or maybe you have a job that needs a special flourish. A Mediterranean touch.
What about adding potted olives, lemons, and figs as a premium choice you can help with.
